# Create an Application Role

API documentation for the FusionAuth Create an Application Role API.

# Create an Application Role

This API is used to create a role for an Application. Specifying an Id on the URI will instruct FusionAuth to use that Id when creating the role. Otherwise, FusionAuth will generate an Id for the role.

note

When creating a role on a universal application, a global API key is required. A tenant-scoped API key is not sufficient for this operation.

## Request

#### Request Headers

`X-FusionAuth-TenantId`Stringoptional

The unique Id of the tenant used to scope this API request.

The tenant Id is not required on this request even when more than one tenant has been configured because the tenant can be identified based upon the request parameters or it is otherwise not required.

Specify a tenant Id on this request when you want to ensure the request is scoped to a specific tenant. The tenant Id may be provided through this header or by using a tenant locked API key to achieve the same result.

See [Making an API request using a Tenant Id](https://fusionauth.io/docs/apis/authentication.md#making-an-api-request-using-a-tenant-id) for additional information.

### Request Parameters

`applicationId`UUIDrequired

The Id of the Application.

`roleId`UUIDoptionalDefaults to secure random UUIDImmutable

The Id to use for the new role. If not specified a secure random UUID will be generated.

### Request Body

`role.description`Stringoptional

A description for the role.

`role.name`Stringrequired

The name of the Role.
